Picked up a Beaglebone black this evening



Also received a big bag of various components from Tayda Electronics, arrived 10 days after I made the order.

I have built a couple of hexapods, so have some experience controlling lots of servos. I would suggest you don't use a for loop and totally forget about the delay function. I just use the millis function. It is not that hard, just take a look at the blink without delay example in the IDE.

I've only tried the example sketches that come with the u8glib so far. But the library is well documented: http://code.google.com/p/u8glib/wiki/userreference Don't think its very hard to show some graphics and text on the lcd

I also bought a cheap 12864zw lcd on Ebay. Got mine to work using spi and the U8glib. http://www.bajdi.com/cheap-128x64-graphic-lcd-12864zw/

I also started building my own clones. I've built some based on the ATmega328P and on the ATmega1284P. I'm not a fan of shields and don't use any. Shields wont fit in my boards. But it makes it easier to design a board
I play a lot with servos, 3.3V I2C sensors and wireless nRF24L01 modules. So I designed a board with a 3A switch mode power supply, an I2C logic level converter and a header for the nRF24L01 module. And I put a row of 5V and GND pins next to most I/O pins. Makes it a lot easier to connect servos and sensors to the micro controller. I designed my boards in Eagle, not that hard to learn, and had the PCB's made by Seeedstudio.

Can you bootload these chips just like an ATmega328? With an Arduino as ISP or USBasp?

Zijn er eigenlijk goede Nederlandstalige boeken om C++ te leren? 

Have you seen this: http://www.jkdevices.com/arduino-megamini
The Eagle files are on github: https://github.com/jkdevices/MegaMini

Very interesting stuff, I use the nRF24L01 modules a lot. Will definitely try out your version of the RF24 library.

What kind of breadboard where you using? 50W @ 12V = +4A. You need some thick wires/traces for 4A.

Hmm, I thought Seeed and Itead had changed their policy on panelizing? Correct me if I'm wrong. http://www.instructables.com/id/Panelizing-PCBs-for-Seeed-Using-Eagle-Free-Light/#step1

I play a lot with servos, so I designed my own board to make it more easy to test code and connect servo to the ATmega328. http://www.bajdi.com/bajduino/bajduino-3a-3/
It has 3A switch mode regulator so it can power a couple of servos without trouble. Has 3 rows of male pins for every input/output.

I'm using 3 Turnigy 8A UBECs. I first tried to power the 18 servos with 2 8A UBECs and blew them up...

Cool walking action, that is quite an accomplishment.

LOL, so it can't carry it's own battery and so has to drag it along? Good thing it's not an aircraft.

Lefty

The servos have enough torque to carry the battery. But the chassis is to small to fit my big 3S 3000mAh Lipo battery and all the electronics. I'm planning to use a slightly bigger chassis so the electronics and battery all fit inside/on top of the chassis.
